Title: Web tip cutting arrangement for dry end of paper making machines
Inventor: FISSMANN HANS-JOACHIM
IPC: D21F5/04
Filed: 1991-12-02
Abstract: WEB TIP CUTTING ARRANGEMENT FOR DRY END OF PAPER MAKING MACHINES            ABSTRACT THE DISCLOSURE          The dry end of a paper making machine includes a first dryer group of heatable web dryer cylinders followed by a second dryer group of heatable dryer cylinders.  Each dryer cylinder having a neighboring suction guide roll.  A respective first and second web support belt for the first and second dryer groups.  The paper web to be dried alternately passing between a dryer cylinder and the neighboring suction guide roll, such that the web comes into direct contact with the dryer cylinders.  A transfer region between the two dryer groups at which the web is transferred from the first to the second web support belt.  A displaceable guide roll in the transfer region and associated with at least one of the first and the second web support belts.  The guide roll is displaceable between a position at which the support belt supports the web and another position at which the displaceable support belt is moved away from the web at one of the dryer groups creating a free length of web between the one dryer group and a detection roll between the dryer groups.  The displaceable guide roll may be the deflection roll between the dryer groups or may be another roll past which passes the same support belt that is passing over the deflection roll.  A web tip cutter is associated with the free length of the web to there produce a starting end of the web for purposes of threading.
Patent CA-2057013-A1 (CA)
IPC: H04W88/02
Filed: 1990-07-09
Abstract: A paging receiver has a synthesizer for governing the receive frequency. The paging receiver further has characteristics which are varied in response to the receive frequency. These characteristics include varying the bandwidth (52) of a loop filter (26) within a phase lock loop (16) within the synthesizer as well as varying the time in which a detector circuit used to extract a DC level from a recovered audio signal is disabled. Furthermore, the bandwidth of the loop filter is varied in response to switching from a first receive frequency to a second receive frequency in order to provide for either a uniform frequency lock time (54) or for a rapid frequency lock time. Furthermore, the time in which the detector circuit is disabled is correspondingly changed.

Title: Self-serve checkout system
Inventor: SCHNEIDER HOWARD
IPC: G07G1/00
Filed: 1992-01-30
Abstract: A self-serve checkout system which consists of a self-service checkout station containing a video camera unit which generally views a first scale where bar coded products are deposited and which pivots to view a second scale where products without bar coded labels are initially deposited. The video camera generates a signal received by a display in a supervisor station which allows a supervisory employee to approve non-bar coded products and to survey in general other products deposited on the first scale. A plurality of self-service checkout stations are selectively connected to a singular supervisor station by a switching unit. The self-service checkout stations contain angled or active surfaces to prevent deposition of articles for later fraudulent removal. The self-service checkout stations contain receipt printers, magnetic payment card readers and coupon acceptors to further reduce the time the supervisory employee must spend on each order.

Title: Rotary machine with oval piston in triangular chamber
Inventor: YANG CHUNG-CHIEH
IPC: F01C1/04
Filed: 1992-03-16
Abstract: Abstract of the Disclosure:    A rotary machine preforming a triangular rotation instead of a linear reciprocating motion comprises an oval rotor set of  to revolve  along a three cylinder walls combined inside a  cylinder block to achieve a new combustion moving function of an  internal combustion  engine with smaller volume,  less weight,  less parts but  stronger power so as serve military vehicle or  vessels  for better capability and efficiency in the field.    The three cylinder walls are incorporated into one unit with a  rotor  (which  serves as a piston in a  reciprocating  engine) rotating   inside  the  machine.    It  performs   the   function approximately three times than a conventional cylinder.  Since no linkage is used,  the crank and most parts are commonly used, the size  can  therefore be greatly reduced while the horsepower  is relatively increased.   Because several intake and exhaust  ports can be simultaneously used during each stroke,  the efficiency in intaking  and  exhausting  stroke  of  this  machine  is  greatly improved  which means the thermodynamics is fully utilized.   The rotor  is  designed  for circulating therethrough  with  air  and engine  oil,  thereby  providing better lubricating  and  cooling effects.   The  rotor is constantly in contact with the  cylinder walls  during  its  rotary  motion  around  a  circle,   a   high compression ratio is simultaneously achieved as expected.

Title: Double lens helmet face shield with electric heating field
Inventor: REUBER DOUGLAS A
IPC: A42B3/22
Filed: 1993-03-02
Abstract: Known protective helmets used for motorcycle riding, flying and snowmobiling employ transparent visors that have heating elements to reduce and attempt to eliminate the build-up of ice, condensation and fog.  A double-lensed face shield is provided with a pair of electrodes formed on an inner face lens, in the air pocket formed between the inner face lens and the outer weather lens.  Substantially across one entire surface of the inner face lens is formed an electroconductive film.  An upper electrode extends from a first end along an upper margin of the inner face lens on the film to a second end.  On the opposite lower margin extends on the film a lower electrode from a first end to a second end.  An insulated contact passes from one side of the inner lens to the other and connects the first end of the lower electrode with a conductor which extends on the opposite side of the inner lens towards the  first end of the upper electrode.  Power supplied across the first end of the upper electrode and the tail end of the conductor will result in electrical flow across the film inhibiting fog, ice and frost.          Also provided is an assembly to permit the installation of face shields on helmets of different sizes and with openings of different configurations.
